More observations

* The cudweed on the allotment site is marsh cudweed (Gnaphalium uliginosum).

* I find the willow-herbs with clavate stigmas a difficult group, but today I identified one on my allotment as pale willow-herb (Epilobium roseum).

* I found that the peppermint (Mentha x piperita) that I'd seen growing along the canal bank in previous years is still present. (I'd previously thought that it might have been eliminated by mowing of the towpath.)

* Walking into the town centre I saw purple toadflax (Linaria purpureum) and purple mullein (Verbascum phoeniceum) growing wild.

* Wild Angelica (Angelica sylvestris) is now in flower along canal banks.
